For all those remote areas where you don’t have GSM coverage, and where you can’t put a Base Station near your UHF RTU’s!
The RA440 bridges UHF RTUs to the GPRS network. It incorporates therefore two radio modems: the same 500mW UHF radio found in our A733 addWAVE RTU, and the same Motorola Quad-Band GPRS modem used in our A753 GSM RTU. That’s why you see on the image of the device 2 antennas!
And that’s also why we call it the “Remote A440” – in contrast to the regular A440, which is connected to the A850 Telemetry Gateway by means of a cable, the RA440 connects to the A850 Gateway by GPRS.
If you need to collect data from a remote area which is not covered by GSM, and if you have no place with mains power and internet or phone connection nearby to install an A850 Telemetry Gateway, then you put up an RA440 in the nearest area which has GSM/GPRS coverage, and from here you reach out to the radio RTU by UHF.
